Sir Ben Ainslie on America's Cup win

Briton Sir Ben Ainslie says Oracle Team USA's dramatic America's Cup victory was physically "one of the toughest races" he has sailed in.

USA overhauled an 8-1 deficit to beat Emirates Team New Zealand in the decider in San Francisco, with four-time Olympic gold medallist Ainslie's team's miraculous turnaround in fortunes down to improved teamwork and renewed belief.

New Zealand were marooned on match point for a week before being defeated, coming within two minutes of glory on Friday before organisers abandoned race 13.
